The same machine is, of course, applicable to the loading and transporting of any loose material which may be picked up by a, shovel. Other means may be used for moving the machine and suitable power for the moving and operation of the machine may be applied in any known manner since my invention is confined to the machine itself and is not concerned with A .the particular exterior means employed for eiecting operation of the shovel and transportation of the machine.v

The machine lcomprises two side frames II) and II preferably constructed of suitable strong material such as steel plate suitably reinforced to withstand the rough uses to which a machine of this character is subjected. The side plates I! and II mount two axles I2 and I3 upon which wheels or rollers such as I4 and I5 are journalled to support the forward end of the machine. At the rear end of the machine the side frames are connected by a cross plate I B. The rear end of the machine is closed at the bottom by a bottom plate I1 that is hinged to the side plates by a shaft I8. This bottom plate has side flanges I9 and 2U located outside the side frames II! and II and extends beyond the cross plate I6 where it is supported by wheels 2|. In dumping the machine the bottom I1 can be opened by moving the wheels 2I over a dump pit so as to allow them and the bottom plate I1 to drop down.

The shaft I8 also pivots a trough member 22 which comprises a bottom plate 23 and two side plates 24 which extend upwardly from the bottom plate 22 and forwardly from the shaft I8 along the inner surfaces of the side frames I3 and II. A suitable pivotal mounting for the trough 22 which is described above, comprises a pipe 25 welded to the under surface of the bottom plate 28 and surrounding the shaft I8. The side plates Y rear top edgesby a cross bar '25 which is welded at its ends to the side plates. This cross bar has an upstanding rib 28 on which two lugs 29 and 30 are provided, the lugs being bent at a slight angle to the rib 28 as illustrated.

At the forward end of the trough near the bottom plate 23 thereof I mount a shaft 3| for supporting a shovel 32. The ends of the shaft .3I are secured in the side plates 24. The shovel 32 has its bottom plate 33 mounted on the shaft 3i by a pipe 34 surrounding the shaft and Welded at the bottom plate 33. 'I'he shovel 32 has its side walls 35V and 36 extended upwardly above the side frames I and II and connected together by cross membersV 31 and 38 which are suitably welded to the side plates. The digging or shoveling front edge 39 of the shovel is shown as serrated in the usual manner and, of course, the common practice of providing a hardened and suitably reinforced digging portion for the shovel is followed in constructing the shovel.

Means for rocking the shovel ahoutits pivot is provided. This means comprises a tackle block lil swiveled by an eye-pin 40 to two upstanding ears 42 provided on the cross'membert 111.@ @edile block has a hook 43 to receive one end of a cable 44 and the cable is trained around a second tackle block 45 which is mounted on an angle iron 46 provided at the top rear end of the machine. The tackle block i5 as shown comprises two pulleys journalled on a pin il that is carried by brackets 158 and 49 secured to and projecting upwardly from the angle iron 45.

'I hecross member 31 has apair oflupstanding lugs 50 and 5I' thereon. These lugs and the lugs 29 and 3!! serve as mounting means for two tie rods 52Vand 53 that are used to limit the downward swinging movement of the shovel 32 about the pivot 3| L 'Ihe tie rods are secured in the lugs 2Q and 3i) by nuts 54 and 55 threaded on the tie rods and adapted to engage opposite sides of the lugs 29 and 3). The lugs 5i) and 5I have elongated slots 55 therein for receiving the tie rods so that a limited amount of playknp and down is provided. The tie rods have their heads 51 cushioned by rubber vcushions 58 bearing against washers 59 that overlie the slots 5t.

In Figure 2 of the drawings I have shown vthe dotted line positions that may be assumed by the shovel and the trough as the machine is loading and crowding the material back into the space over the bottom plate I1 between the side frames I and II. The loading operation Vstarts with theparts in the full line position shown in Figure 2 and by manipulation of the cable 44 the shovel'can be made to work its way into the material. The machine is drawn forward by any suitable vmeans such as the chains E!! and 5I which are secured "to the'side frames II! and VII and connected lto a suitable cable which is usually trained over a tackle block anchored at the face of the stope or tunnel. When the shovel isrloaded it isv tilted up by tightening the cable 44 so as to dump the material gathered on the shovel back upon the trough 22. The trough 22 and the shovel are supported against downward movement by supporting brackets 63 which are mounted on the side frames III and II beneath the forward end of the trough 22. The tendency of the trough and shovel to buckle where they are pivoted together by the shaft 3l is preventedy by the rods 52` and 53. The length of the rods 52 and 53 can be adjusted by means of the nuts 5s and 55 threaded thereon so as to limit the lower position of the vshovel as desired by the operator. shovel and then using the cable 44 to rock the shovel about the shaft 3| and to rock both the trough andthe shovel about the shaft I8 to crowd the material back into the body of the machine onto the bottom plate I1 and against the back plate IB. When the machine is loaded it is drawn back to dumping position by means of a cable 44 where the bottom plate I1 is per-- mitted to"drop to empty the machine. The ma chine is then drawn forward by the chains Si! and 5I and the loading operation is repeated.

It is desirable to avoid the piling up of material around the front wheels or rollers I5. In order to avoid the possibilityof'rock crowding down between the shovel 32 and the front wheels Vduring the filling operation,"I pivot a plate 54 on The 'loading progresses by filling theY agareevsn s of springs 68"separated"1byspacersw'to thelrcar ends of thepipes 61; There are two-of thepipes (i1,r one at' each-` side `of the machine-andffboth pipes are provided with Springsinthemanner show-n inFigure 9. Therear ends'lof'the cables.` areprovidedwith headsf1`thatbear against: the rear spring beandare-thus always under tension to lift the plate 64 when theshovel is: raised. Of course, in theuppermost position of the shovel, the shovel moves= away from the plate 6ft which is stopped byy reaching the upper limit to which the cables 55 can move it; However,

whenthe shovelV isl-again lowered it-` engages the plate fili` and forces the plate downA againstl theA tension of the springs 68. Af multiplicity of springs 68 isV used in order to simplify the adiustment of theamount of p tension on the cable E35 and to simplify-the acquisition of the springs and replacement thereof: in'. the event that a spring fails. A cap 1| is provided. onxthefrear,-` end of each pipe 6,1 to provide accesstothe cable.

Any suitable type of support may be used to mount the machine for movement overl the ground. The wheels orrollers' shown are Imerely examples of known supports. Other supports of a skid type or caterpillar type wouldserve-equally well. For purposesof illustration I have shown in Figures 5 and 6 one type of roller and bearing that is used. The roller is made up with a heavy tubular section 12 and to this section is welded a bearing support sleeve 13. A spacing ring 14 :is secured on the axle such as I2 or I3 by suitable set screws 15. Two roller bearings 16 and i are inserted in the sleeve 13 on opposite sides of the ring 14 and, retaining plates 18 and 19 are bolted to the ends of the sleeve 13 to keep the bearing in place. As shown, I provide at least three of the rollers on each shaft to give adequate support to the machine and its load. It is obvious, of course, that various types of supporting means may be used for carrying the machine within the scope of my invention as the invention is not concerned with the details of the supporting means.

Referring now to Figures 7 and 8, in this form of the invention I have illustrated my improve`- ments as applied to a machine wherein rear dumping is employed. In this machine side frames Si), similar to the side frames Ii) and il are provided and these side frames are connected together by axles 8l and 82 and a top cross bar e3. There is also a rear angle iron cross bar 84 connecting the side frames. The machine is provided with a rear gate 85 pivoted at 85 and close ing the rear end of the machine. Suitable latches Si? are pivoted on the side frames 80 and engage laterally extending bars 88 on the gate 85. In this form of the invention the entire bottom of the machine is formed by pivoted troughs and a shovel. There are two pivoted troughs 89 and et and the shovel is indicated by the numeral e I. A rear shaft 92 pivots the rear lower end of the trough 89, the shaft being mounted in the side frames 55B. The front end of the trough 89 is limited in its downward movement by brackets on the side frames Si). The trough 8G is pivoted at its rear lower end by a shaft 94 which is secured to the side walls of the trough 89. Downward movement of the trough 90 is limited at its front end by brackets 95 which are secured on the side frames 80. The shovel 9i is pivoted on a shaft 95 that is carried by the side walls of the trough 9i?. In order to prevent buckling up of the parts about the shafts 94 and 96 the troughs 89 and 90 are linked together by connecting rods Si 911 which-arecsimilar-in all'respectsnto the:` conf-V. nectingrodsiZ`- and 5.3.
